我正在创建银行业务界面，我希望每年每10秒钟应用一次利息（作为修改后的时标的一部分）。

我使用了time.sleep()，但在我看来它也阻止了用户界面的工作。
有人知道有什么变通办法或方法将time.sleep()函数限制在循环中吗？

您的while循环永不中断，以允许程序的其他部分运行。
答案 1 :(得分：0)
尝试使用threading，将更新savings和fixdeposit的部分移至另一个线程。这是一个有效的示例，我只截断了部分不变的代码，您每隔10秒钟就会看到updating打印一次：
import threading
import time
customers = 100
savings = []
fixdeposit = []
ask_user_type = ...
employee_function_options = ...
customer_function_options = ...
for i in range (100):
savings.append(1000)
fixdeposit.append(0)
def regular_update():
global savings, fixdeposit
while True:
time.sleep(10)
print('updating')
savings = [i * 1.04 for i in savings]
fixdeposit = [i * 1.07 for i in fixdeposit]
my_thread = threading.Thread(target=regular_update, args=())
my_thread.start()
user = int(input(ask_user_type))
... everything here as in your code
答案 2 :(得分：0)
while 1 == 1:
time.sleep(10)
savings = [i * 1.04 for i in savings]
fixdeposit = [i * 1.07 for i in fixdeposit]
由于while循环中的条件1 == 1，它永远执行，因为程序无法从内部中断。这意味着您的time.sleep(10)无限期运行。
更新： 假设您希望用户输入 valid （取决于您定义的有效内容），则可以执行以下操作之一：
number = (int)(input("Enter a number: "))
# 3 is just chosen here as a representative value
# The loop will run until 3 is received as input
while number != 3:
number = (int)(input("Enter a number: "))
print("Exited loop")
或者您可以使用break语句在满足条件时退出循环：
# 3 is just chosen here as a representative value
# The loop will run indefinitely, but if 3 is received as input, it will break the loop (force it to exit)
while 1 == 1:
number = (int)(input("Enter a number: "))
if number == 3:
break
print("Exited loop")
